(Astronauts pounded a “drive tube” into the lunar ground to pull a core of material, weighing about 800 grams.) Astronauts on Apollo-era moon-landing missions brought many rock samples down to Earth; these were vacuum-sealed and have never been exposed to our atmosphere.
But one thing was certain: on Orion’s first foray beyond Earth, a crew-less capsule would complete a six-day circuit of the moon; that’s the mission Bridenstine now says could launch atop a commercial rocket.
Trump's Budget Guts Science Agencies—But Favors the Moon Trump's budget would cut the Environmental Protection Agency's science and technology programs by 40 percent, while research on climate change science would drop from $95 million to $32 million.
This week, the Hubble Space Telescope found evidence of a newborn star about 1,000 light years from Earth in a nebula called NGC 1333.
The Beresheet lander is a joint venture between Israeli nonprofit SpaceIL —one of the participants in the Google Lunar X Prize, which challenged private companies to land spacecraft on the moon without government funds—and Israel Aerospace Industries, the country's largest aerospace and defense company.
“When I see all these headlines about the wolf blood super moon, I go nuts,” says Fred Espenak, scientist emeritus at NASA’s Goddard Space Flight Center.
(In the case of our moon, astronomers think it once whirled faster about its axis.) But over time, gravity from our planet exerted torque on bulges in the lunar surface, forcing its rotation into synchronization with its orbital period.
50 Years Ago, Earthrise Gave Us the View of a Lifetime Bill Anders/NASA Half a century ago, astronauts aboard NASA's Apollo 8 mission become the first humans to leave low Earth orbit, traverse the 240,000 miles separating our planet from its moon, and loop around that natural satellite to look upon its forever-hidden far side (not dark side) with their own eyes.
But while concrete attribution remains elusive, a wave of recent digital attacks has led some security analysts to suggest that Iranian state-sponsored hackers may have ramped up their digital assaults against the US and Europe as well."If you look at these groups, they’re not hacking for money, what they’re doing is very much nation state motivations," says Eric Chien, a fellow in Symantec's security technology and response division.
Security experts warn that Russia and China are both catching up and developing anti-satellite weapons capable of tripping up America’s strategic orbital foothold.The fourth thing to know about space power is, if America gives up its military dominance, expect its economic influence to wane as well.
