WASHINGTON — The competition for the moon between the Unites States and China is being closely watched by the Defense Department as the military expects to play a role protecting U.S. access to cislunar space.

One concern for the Pentagon is the possibility that China establishes a presence on the moon before the United States and tries to set the international rules of behavior in space, said Brig. Gen. Steven Butow, director of the space portfolio at the Defense Innovation Unit.

DIU is a Defense Department organization based in Silicon Valley that works with commercial vendors developing technologies relevant to national security.

NASA astronauts Bob Behnken and Doug Hurley now face the phase of the flight that Elon Musk said is his “biggest concern.”

It’s been a long time since there’s been anything like “regular order” in the congressional appropriations process: individual bills passed by the House and Senate, their differences resolved in conference to produce a final version that’s signed into law before the beginning of the fiscal year October 1. Instead, there are usually stopgap funding bills, called continuing resolutions, that extend for weeks or months before a massive omnibus bill, combining up to a dozen different bills, is eventually passed.

Fiscal year 2021 is not going to be the year regular order returns to the appropriations process. The pandemic took hold in the early phases of the appropriations process, just as Congress was starting its usual series of hearings on various parts of the administration’s budget proposal released in early February. Congress instead devoted its attention to series of relief packages during the limited time it was in session this spring.

With no hearings about NASA’s budget proposal by either House or Senate appropriators, the first sign of their views about the agency’s budget had to wait until a few weeks ago. On July 7, the House Appropriations Committee released its draft of the commerce, justice, and science (CJS) spending bill that includes NASA. That bill provides $22.6 billion for NASA, the same amount the agency received in 2020. The White House, by comparison, asked for $25.2 billion for NASA.

While the robotic missions launching to Mars this year have a wide range of science goals, they are widely seen as precursors for eventual human missions to the Red Planet. NASA’s Mars 2020 mission includes an experiment called MOXIE that will demonstrate a way to produce oxygen from the carbon dioxide in the Martian atmosphere, a capability that will be essential for future human expeditions. NASA’s fiscal year 2021 budget proposal included a request to start work on a Mars Ice Mapper mission, an orbiter that would search for subsurface ice deposits that could be resources for future human expeditions.

Much of the planning for future Mars missions is focused on various capabilities needed to safely transport humans to the surface of Mars and bring them back. But beyond technologies like in situ resource utilization and supersonic retropropulsion are more mundane, but no less essential, matters: How will the crew eat? How will they deal with boredom on the long mission? How will they get along with one another in a confined space?

Dragon to the Moon?

The following memo was sent by the author to NASA administrator Jim Bridenstine and Scott Pace, executive secretary of the National Space Council, on June 30, 2020.

A mission equivalent to Apollo 8—call it “Artemis 8”—could be done, potentially as soon as this year, using Dragon, Falcon Heavy, and Falcon 9.

The basic plan is to launch a crew to low Earth orbit in Dragon using a Falcon 9. Then launch a Falcon Heavy, and rendezvous in LEO with its upper stage, which will still contain plenty of propellant. The Falcon Heavy upper stage is then used to send the Dragon on Trans Lunar Injection (TLI), and potentially Lunar Orbit Capture (LOC) and Trans Earth Injection (TEI) as well.

The Russian startup StartRocket is developing a “Foam Debris Catcher,” a small, autonomous satellite that would snag and de-orbit space debris using sticky polymer foam.

SpaceX pushed a massive tank for its latest Starship prototype beyond its limits Tuesday (June 23) in an intentionally explosive test in South Texas.

The Starship SN7 prototype tank ruptured during a pressure test at SpaceX’s Boca Chica proving grounds, the second in just over a week for the spacecraft component. But where a June 15 test resulted in a leak, Tuesday’s test was a bit more dramatic.

A human embryo editing experiment gone wrong has scientists warning against treading into the field altogether.

To understand the role of a single gene in early human development, a team of scientists at the London-based Francis Crick Institute removed it from a set of 18 donated embryos. Even though the embryos were destroyed after just 14 days, that was enough time for the single edit to transform into “major unintended edits,” OneZero reports.

Human gene editing is a taboo topic — the birth of two genetically modified babies in 2018 proved incredibly controversial, and editing embryos beyond experimentation is not allowed in the U.S. The scientists in London conducted short-term research on a set of 25 donated embryos, using the CRISPR technique to remove a gene from 18 of them. An analysis later revealed 10 of those edited embryos looked normal, but that the other eight revealed “abnormalities across a particular chromosome,” OneZero writes. Of them, “four contained inadvertent deletions or additions of DNA directly adjacent to the edited gene,” OneZero continues.

WASHINGTON — For the second time in less than 18 months, SpaceX has abandoned plans to build a manufacturing facility at the Port of Los Angeles for its next-generation Starship launch vehicle.

In a March 27 letter obtained by SpaceNews, SpaceX notified the Port of Los Angeles that it was terminating a lease approved just a month earlier for a parcel of land at the port. News of the lease termination was first reported by the Los Angeles Times.

The letter, signed by Bret Johnsen, SpaceX’s chief financial officer, served as a 45-day notice of SpaceX’s intent to terminate the lease, making the effective end date of the lease May 11. The letter did not explain why the company was terminating the lease.

In May, NASA announced its intent to “establish a common set of principles to govern the civil exploration and use of outer space” referred to as the Artemis Accords.[1,2] The Accords were released initially as draft principles, to be developed and implemented through a series of bilateral agreements with international partners.

The Accords offer the possibility to advance practical implementations of long-held principles in the Outer Space Treaty (OST). They raise a rich set of policy questions as we begin to take the law into new levels of resolution. This bold pursuit of uncharted territories is to be applauded, and yet, there is also the risk of diverging from 53 years of international law.

One the ten principles is focused on Deconfliction of Activities, with “safety zones” named as a specific mechanism of implementation:
