Virgin Orbit Traces Cause Of LauncherOne Engine Failure To Propellant Line
An engine failure that cut short the first test flight of Virgin Orbit’s air-dropped LauncherOne rocket in May was caused by a faulty propellant feed line, the company’s CEO said this week.
Virgin Orbit’s first orbital launch attempt May 25 ended seconds after the rocket’s release from a Boeing 747 carrier jet over the Pacific Ocean. Dan Hart, Virgin Orbit’s CEO, said Wednesday that engineers traced the cause of the premature shutdown of the first stage’s engine to a break in a propellant feed line.
The 70-foot-long (21-meter) LauncherOne rocket is designed to place small satellites into orbit. The first test flight of the air-launched rocket in May was the culmination of years of development, including numerous engine tests and test flights of the modified Boeing 747 carrier aircraft.

NASA Safety Panel Has Lingering Doubts About Boeing Starliner Quality Control
Members of a NASA safety panel expressed continued concern about quality issues with Boeing’s commercial crew spacecraft while cautiously supporting SpaceX’s plans to fly reused spacecraft on future crewed missions.
During a July 23 teleconference by the Aerospace Safety Advisory Panel, members discussed several reviews of issues with the uncrewed flight of Boeing’s CST-100 Starliner spacecraft last December. NASA announced July 7 it had completed its reviews of that Orbital Flight Test (OFT) mission, which resulted in 80 recommendations specific to the flight and several more from a separate “high-visibility close call” review carried out earlier this year by NASA.

NASA’s Mars Rover Loaded Up With Nuclear Power Ahead Of Next Week’s Launch
NASA’s Perseverance rover destined for Mars next week has completed another step in preparation for launch – installation, and activation of its nuclear power source.
“The #MarsPerseverance MMRTG [multi-mission radioisotope thermoelectric generator] is installed and doing well. This Red Planet dune buggy is fueled and ready to go!” wrote Tory Bruno, CEO of launch provider ULA, via Twitter on Wednesday. He further clarified what this process means in response to a question about the power source. “RTGs [radioisotope thermoelectric generators] are ‘activated’ at the moment of assembly because the radio source continuously generates heat which solid state thermoelectric devices turn into voltage.”

Mission Extension Vehicles Validate New Satellite Lifeline in Orbit
Until February 2020, when a satellite on orbit ran out of propellant, that was the end of its life. Most major communications and military satellites are designed with prolonged lifetimes and carry enough fuel for a 15 year mission.
But the struggle for some satellite operators has been that at the end of that 15 year period, satellites running out of fuel are still working perfectly well in every other regard. Therefore, perfectly good satellites have to be decommissioned. But not anymore.

The Doctor From Nazi Germany and the Search for Life on Mars
When Penelope Boston was a student at the University of Colorado in the 1980s, she wanted to create a miniature Mars and see how some living things fared on it.
Fundless, she amassed parts from labs around campus and bootstrapped a basic version of what scientists sometimes call a Mars Jar: a sealed container whose insides resemble the red planet, used to test the survival of biological beings. Dr. Boston had read about Carl Sagan’s use of Mars Jars and had assumed, as many did, that he’d invented them.

NASA Rover Launch Gets Additional Safety Precautions
NASA is taking additional safety measures for the launch of its Mars Perseverance rover next week from Cape Canaveral. That’s because it’s packed with radioactive material.
The NASA rover relies on marshmallow-sized chunks of plutonium for power. As the material decays it gives off heat which the rover can turn into electrical power.
NASA conducted an extensive safety assessment before launch, consulting federal, state and local authorities about the risks and safety measures needed to protect area residents.

Unfavourable Laws, Policies Hinder Private Participation In India’s Space Journey
While the Indian government is working towards allowing end-to-end private participation in the country’s space sector, experts point out that India’s legal and policy hurdles pose a serious hindrance.
Highlighting one such policy, an expert noted how an Indian satellite-maker has to pay 18% GST for launch while foreign makers are exempt from such taxes.
“An Indian satellite-maker must pay 18% GST to launch satellites on ISRO’s rockets, whereas a foreign customer can do the same without paying any GST, as the launch services provided to them (foreign firms) qualify as “export of service” which are exempt from the levy of GST.

Why Japan Is Emerging As NASA’s Most Important Space Partner
The first time the US went to the moon, it put down an estimated $283 billion to do it alone. That’s not the case with Artemis, the new NASA program to send humans back. Although it’s a US-led initiative, Artemis is meant to be a much more collaborative effort than Apollo. Japan is quickly emerging as one of the most important partners for this program—perhaps the most important.
Although NASA has teased for quite some time the idea of a pretty ambitious role for Japan in Artemis, that talk finally became real on July 9, when the two countries signed a formal agreement regarding further collaboration in human exploration. It gives NASA a much-needed partner for Artemis—without which the agency would find it much more difficult to meet the long-term goals of establishing a sustainable permanent presence on the moon.

The US Needs To Take Action To Deter Near-Peer Rivals In Space
Earlier this June, the Department of Defense released the unclassified summary of its 2020 Defense Space Strategy, which openly designates space as a “distinct warfighting domain,” a distinction that only recently gained national policy acceptance. With this document, the DoD now has the authorization to begin preparing to deter potential space adversaries, and should deterrence fail, to win a conflict that extends into space.
This important update to the near-decade-old National Security Space Strategy follows an April announcement by U.S. Space Command that Russia conducted a direct-ascent anti-satellite (DA-ASAT) missile test that is purportedly capable of destroying low-Earth orbit satellites. This test stands in stark contrast to Russia’s frequent claims that it has tried to prevent an arms race and avoided introducing weapons into space.

Roar of the Bumper: Remembering the Cape’s First Launch, 70 Years On
For decades, we have grown used to watching launches from Cape Canaveral. But until the arrival of the rockets and the rocketeers, the Cape was a sleepy place, characterized by dense thickets of cane vegetation and home to scattered farming and fishing communities, as well as alligators, racoons, scorpions and ubiquitous mosquitoes. When the first military personnel arrived here to set up the Army’s Long Range Proving Ground in early 1950, a joke soon made the rounds that the security detail would bed down in their tents each night, only to awaken the next morning to the most unwelcome of bedfellows: a bunch of fearsome rattlesnakes. It is hard to imagine, seeing what we see today, what a different world this place once was. And on 24 July 1950—70 years ago today—the Cape observed its very first rocket launch with the flight of Bumper 8.
