NASA’s OSIRIS-REx Asteroid Sample Return Mission now knows much more about the material it will be collecting in just a few weeks.
Goddard’s Amy Simon found that carbon-bearing, organic material is widespread on the asteroid’s surface, including at the mission’s primary sample site, Nightingale, where OSIRIS-REx will make its first sample collection attempt on Oct.20.
These and other findings indicate that hydrated minerals and organic material will likely be present in the collected sample.

NASA said Saturday that the launch of four astronauts on SpaceX’s first operational Crew Dragon mission to the International Space Station has been delayed from Oct. 31 until “no sooner than early-to-mid November,” allowing time for SpaceX to resolve an issue with Falcon 9 rocket engines that halted a recent launch attempt with a GPS navigation satellite.
The engine concern appeared during an Oct. 2 launch attempt of a Falcon 9 rocket with a GPS satellite at Cape Canaveral, prompting computers controlling the final seconds of the countdown to abort the mission just two seconds prior to liftoff.
Elon Musk, SpaceX’s founder and CEO, tweeted after the abort that the countdown was stopped after an “unexpected pressure rise in the turbomachinery gas generator,” referring to equipment used on the rocket’s Merlin main engines. The gas generators on the Merlin 1D engines drives the engines’ turbopumps.
California-based researchers develop a test that can detect the coronavirus using gene-editing technology and a modified mobile phone camera.
The long-term goal is to get UN guidelines picked up as national licensing regulations.
Astronomers have studied the megaconstellation threat, alerted the public about it and helped satellite operators dim their spacecraft. But some scientists are now taking another step, one that they hope will have even more significant and lasting effects.
An online app called Amica is now using artificial intelligence to help separating couples make parenting arrangements and divide their assets.
For many people, the coronavirus pandemic has put even the strongest of relationships to the test. A May survey conducted by Relationships Australia found 42% of 739 respondents experienced a negative change in their relationship with their partner under lockdown restrictions.
There has also been a surge in the number of couples seeking separation advice. The Australian government has backed the use of Amica for those in such circumstances. The chatbot uses artificial intelligence (AI) to make suggestions for how splitting couples can divide their money and property based on their circumstances.

That was exciting but our goal was to teach people how to test expression in human cells, perform ELISAs &c. and that was more important.
People wrongly think I am completely against the FDA. I’m not. They are good at what they do i.e. helping drug companies make money by making mass produced drugs that help the most amount of people and hurt the least amount of people.
The drug approval process is long and slow so people don’t get hurt. But in a pandemic, time equals lives lost and while they are moving fast on the FDA timescale it is slow on the human lives timescale.
Still there is so much more to drug development including individual outcomes that the FDA is terrible with.
