Why DARPA is Pursuing a Reusable Spaceplane
Here’s a phrase that’s not repeated everyday in the space community: “You’ve heard Elon’s comments … we want to go beyond that,” Brad Tousley, the head of the tactical technology office at the Defense Advanced Research Projects Agency, said May 15.
Elon, of course, is Elon Musk, the optimistic, and some say visionary, founder of SpaceX with plans of eventually colonizing Mars. After landing three first-stage rockets, Musk has said SpaceX would inspect the rockets with plans to later re-fly most of them.
Tousley oversees DARPA’s space programs, which often handles the Defense Department’s most difficult development challenges. He described the landing of first stage rockets by SpaceX and Blue Origin as “very, very impressive accomplishments.” But during a speech at the GEOINT 2016 conference here, Tousley said the agency’s experimental spaceplane, known as XS-1, also has ambitious plans.
“We want to launch again in 24 hours,” he said. Ideally, DARPA’s XS-1 spaceplane would launch 10 times in 10 days and carry payloads weighing as much as 1,360 kilograms into low earth orbit for $5 million.

NASA Probes Witness Powerful Magnetic Storms Near Earth
Explosive storms spawned by interactions between the magnetic fields of Earth and the sun can endanger satellites, spacecraft and astronauts in space, as well as power grids on Earth. Now, a fleet of NASA spacecraft has for the first time directly witnessed the mysterious way in which these magnetic explosions occur.
This work could help shed light on dangerous solar outbursts and help improve the design of advanced nuclear reactors, researchers said. The discovery was made using NASA’s Magnetospheric Multiscale mission (or MMS for short), which launched four spacecraft into Earth’s magnetosphere, the bubble of plasma controlled by the planet’s magnetic field.
“We hit the jackpot,” study co-author Roy Torbert, deputy principal investigator of MMS, said in a statement. “We were able to perform the first-ever physics experiment in this environment.”

Upgraded Antares Rolls Out to Virginia Launchpad, High Stakes Engine Test Looms
An upgraded version of Orbital ATK’s commercially developed Antares rockethas at last rolled out to its launch pad on the Virginia shore – thus paving the path for a high stakes first stage engine test looming “in the next few weeks,” according to the aerospace firm.
“This stage test paradigm is a design verification test, said Kurt Eberly, Orbital ATK Antares deputy program manager, in an interview with Universe Today. The rocket will be erected at the pad during the full power hot fire test which is scheduled to last approximately 30 seconds. Hold down restraints will keep the rocket firmly anchored at the pad.

Here’s What Elon Musk Plans to do with the 3rd SpaceX Rocket he Managed to Land
After recent successes, SpaceX is going to need a bigger trophy room. So far, the private spaceflight company has safely landed a total of three rockets after launching them into space.
Following a successful landing of the first stage of a Falcon 9 at Landing Zone 1 in Cape Canaveral on December 22, the company outdid itself by landing two more first stages on the “Of Course I Still Love You” drone ship at sea. It nailed the ocean landing first on April 8 and then again on May 6 under even more difficult conditions.
The three successful landings bring SpaceX closer to achieving its goal of reusing rockets, which could potentially cut the cost of spaceflight by millions of dollars. And now, as CEO Elon Musk joked in a recent tweet, the company is running out of storage space.

Fireball 10x Brighter than Full Moon Explodes in Big Boom Over Finland
A fireball 10 times brighter than the full moon exploded in the sky of Finland on May 12, 2016. The disintegrating blue-green ball of fire emitted a powerful and loud boom reported all across southern Finland.
The meteor flew from north to south and was 10 times brighter than the full moon, according to first calculations. The ‘shockingly gorgeous’ falling space rock was reported more than 100 times all over southern Finland.
The blue-green meteor flew up to 8 seconds before exploding in a loud sonic boom. This unusually bright object travelled through the Earth’s atmosphere at 16 kilometers per second and disintegrated at about 89 kilometers altitude.

Tiny Debris Chipped a Window on the Space Station
A spacecraft orbiting the Earth gets damaged by space debris. You’re probably thinking it’s the plot of Gravity, and you’re not wrong.
It’s also what happened to the International Space Station a few months ago. Don’t panic, everyone’s fine, and the ISS is still safe. But the 7mm-wide dent in one of the windows of the ISS’s cupola is a reminder that space debris is a force to be reckoned with.
Astronaut Tim Peake took the image of the damage, saying “I am often asked if the International Space Station is hit by space debris. Yes – this is the chip in one of our Cupola windows, glad it is quadruple glazed!”
The ESA and NASA believe that the damage was caused by something tiny, no more than a few thousandths of a millimeter across, crashing into the window at high speed. Likely candidates are a paint chip or a small piece of metal.

The Rise and Fall of Martian Lakes
There is a wealth of evidence, collected over the past few decades, that suggests liquid water was abundant in the early history of Mars – one of our nearest and most studied neighbours. However, the size, evolution and duration of standing bodies of water, such as lakes, on Mars’ surface are still a matter of great debate. A recent study, using data from several spacecraft operating at Mars, paints a detailed picture of the rise and fall of standing bodies of water in a region of Mars which once hosted one of its largest lakes.
Mars’ surface is speckled with basins thought to have once hosted extensive lakes and rivers. The basins left behind by these long since dried-up bodies of water capture an important record of the geological and environmental conditions endured by the regions and make them prime candidates for exploration and study.
A recent paper, published in the Journal of Geophysical Research-Planets, describes a study carried out by Solmaz Adeli, Ernst Hauber, Laetitia Le Deit, and Ralf Jaumann, of an area of Mars’ surface known as the Terra Sirenum region, which is thought to have played host to one of the largest lakes on Mars.

A Year of Mystery Swirls Around Latest X-37B Mission
The semi-classified X-37B robot spaceplane hasn’t received much attention, despite the fact that it is on its fourth flight in space. At least, that’s the official story. Launched in May 2015, the latest mission seems even more covert than the three previous launches. Absolutely no images of the spaceplane were released before launch. That’s a big change from the past, when we saw high-resolution images of the vehicle before launch and after landing.
Nobody knows when X-37B is coming home. It’s even possible that the US Air Force, which owns the small vehicle, has not set a firm date. But we can consider what will happen when it does. This analyst will speculate that no images or video of X-37B will be released after its landing. Again, that would be a departure from previous trends, but consistent with the “no photography” policy of this flight.
Why is X-37B so camera-shy this time around?

NASA Orion Spacecraft Doesn’t Crack Under Pressure
The Orion capsule will launch in 2018 as part of NASA’s “Journey To Mars,” which aims to put humans on the Red Planet around the 2030s (realistically, probably later). Although this particular craft will only go into lunar orbit, and it won’t carry astronauts, it still needs to be airtight so engineers can ensure the first crewed Orion flight in the 2020s will be safe for its human passengers.
To make sure the body is welded together properly, NASA engineers are putting pressure on the capsule. Or more specifically, they’re pumping it full of air to expose any weak points. The capsule is meant to withstand a pressure of about 15 psi, whereas this test pumped it up to almost 19 psi.

First Boeing Starliner Hull Assembled as First Crew Flight Delays to 2018
As completion nears for the prototype of Boeing’s first Starliner astronaut taxi, the aerospace firm announced a slip into 2018 for the blastoff date of the first crewed flight in order to deal with spacecraft mass, aerodynamic launch and flight software issues, a Boeing spokesperson told Universe Today.
Until this week, Boeing was aiming for a first crewed launch of the commercial Starliner capsule by late 2017, company officials had said.
The new target launch date for the first astronauts flying aboard a Boeing CST-100 Starliner “is February 2018,” Boeing spokeswoman Rebecca Regan told Universe Today. “Until very recently we were marching toward the 2017 target date.”

NASA Funding Research in Cryogenic Sleep Chambers, Other Future Technologies
Technology designed to place astronauts in a state of induced hibernation and use lasers as a propulsion system for miniature spacecraft are among the projects that have received a second round of funding through NASA’s Innovative Advanced Concepts (NIAC) Program.
In total, the US space agency has selected eight proposed missions which they feel “have the potential to transform future aerospace missions, introduce new capabilities, and significantly improve current approaches to building and operating aerospace systems.” Each proposal has been awarded a Phase II grant that could be worth up to $500,000 over two years.
Among those proposals is one that intends to create technology that would place astronauts in what Popular Science refers to as “an state of advanced hypothermia,” causing their core body temperature to drop nearly 10 degrees and reducing their metabolic rate during the nine month journey to Mars. Along the way, the machine would also feed them intravenously, according to lead researcher John Bradford and his colleagues at Spaceworks Engineering.

These Space Rocks Could Save the Planet
The box was inconspicuous, but Lawrence Livermore National Laboratory (LLNL) postdoctoral researcher Megan Bruck Syal immediately knew its contents: two meteorites around the size of walnuts. They formed about 4.6 billion years ago and survived a history of violent collisions in the asteroid belt before being bumped into a near-Earth-object orbit by gravitational interactions with the planets.
After finally raining down on Earth, these rocks were scavenged in Antarctica by researchers, sorted and classified at NASA Johnson Space Center, then mailed first-class to Bruck Syal.
Now that these space rocks are in Bruck Syal’s hands, they are mere months away from fulfilling their destiny. They are to be vaporized by a high-powered laser, and the data they yield on asteroid deflection could one day save the planet.

Big Leap: Indian Space Agency Sets Sights on Homemade Space Shuttle
The Indian Space Research Organization (ISRO) is embarking on a landmark experiment to create India’s very own “space shuttle.” In what has been touted as the country’s first attempt, the agency is taking baby steps toward fully developing its own version of its space shuttle.
If the experiment, which is likely to be carried by the end of this May, is successful, scientists are hopeful this could reduce the cost of space launches by up to $2,000 per kg – a significant achievement.
Speaking to Sputnik about the upcoming event, Dr K Sivan, director of ISRO’s Vikram Sarabhai Space Centre, said: “It is a small experiment we’re doing. This is nowhere near to a fully developed shuttle but only a step forward toward that. There are many many technologies required for that. What we’re trying is putting one such technology into the experimental stage.”

Mining Issues in Space Law
Last week, Deep Space Industries, a company with long-term asteroid mining plans, announced a joint venture with the government of Luxembourg to develop a technology demonstration satellite. The spacecraft, dubbed Prospector-X, will be a 3U CubeSat that will fly in Earth orbit at a date to be announced to test technologies needed for future missions to prospect, and eventually extract resources from, near Earth objects.
Planetary Resources, another space resources company, already launched its first tech demo satellite, Arkyd 3R, also a CubeSat, last year from the International Space Station. (The “R” designates it was a reflight of the original Arkyd 3, lost in the Antares launch failure in October 2014.) The company is planning to launch two more tech demo satellites later this year, company vice president Peter Marquez said during a panel last week, as part of a roadmap of missions leading up to the company’s first mission to an asteroid in 2020.

US, Russia Step Up War of Words Over Missile Shield
The United States and Russia on Friday accused each other of mounting an aggressive military presence in northern Europe, with Moscow vowing to “end threats” posed by a US missile shield near its border.
The stepped-up war of words came as Poland on Friday broke ground on the northern section of a US missile defence shield launched in Romania a day earlier, which Russia slammed as a serious security threat despite US assurances to the contrary.
Russian President Vladimir Putin on Friday warned Washington that Moscow will consider measures to “end threats” from the US anti-missile systems in Europe but said it would not be engaged in a new arms race.

India Successfully Test-fires Supersonic Interceptor Missile
In its effort to have a full fledged multi-layer Ballistic Missile Defence system, India on Sunday successfully test-fired its indigenously developed supersonic interceptor missile, capable of destroying any incoming hostile ballistic missile, from a test range off Odisha coast.
The interceptor was engaged against a target which was a naval version of Prithvi missile launched from a ship anchored inside Bay of Bengal, taking up the trajectory of a hostile ballistic missile.
The target missile was launched at about 11.15 hours and the interceptor, Advanced Air Defence (AAD) missile positioned at Abdul Kalam island (Wheeler Island) getting signals from tracking radars, roared through its trajectory to destroy the incoming hostile missile in mid-air, in an endo-atmospheric altitude, the sources said.

Policy Bill Aims to Tame Cost-Plus Contracts
Responding to fears the US military’s technological superiority is at risk, the Senate Armed Services Committee advanced an annual defense policy bill that would open competition to commercial industry, seen as a spur to innovation and cost-efficiency.
The marquee change, if the SASC’s version of the 2017 National Defense Authorization Act passes Congress and is signed by the president, is the proposed closure of the Pentagon’s chief weapons buyer’s office and reassignment of its duties to two new defense undersecretaries for innovation and acquisitions management. It also contains far-reaching language to curb a major concern of SASC Chairman John McCain: cost-plus contracts.

Scientists Reveal What We will Need to do to Survive Doomsday
Concerned scientists have revealed how we can prevent the human race from being wiped out — and it involves either changing our planet’s orbit or uploading ourselves into machines.
In around 500 million years, scientists believe that the Sun’s expansion will leave our planet completely uninhabitable, with conditions so unforgiving that the Earth will return to being the scorched, lifeless lump of rock it once was. However, there is still hope for Earth’s future inhabitants, as researchers claim there are extreme measures we may be able to go to in humanity’s hour of need.
Columbia University astrophysicists Michael Hahn and Daniel Wolf Savin explain how life on Earth will slowly begin to decline in an essay entitled ‘How to Survive Doomsday’. Assuming that humanity can avoid a self-inflicted nuclear apocalypse or a deadly asteroid strike, our species has less than 500 million years left on the planet.

Donald Trump Prioritises Earth Over Space as Spending Priority
Donald Trump has hinted that space exploration could face a fight to protect its share of public spending should he win the US presidential election in November.
Early in the campaign he made clear that earth should be a greater priority. “Right now we have bigger problems, you understand that, we’ve got to fix our potholes. You know we don’t have exactly a lot of money,” he said in New Hampshire.
Interviewed in writing by Aerospace America, the billionaire mogul and Republican frontrunner appeared cool towards committing large amounts of public money to the US space programme.
