Here’s your chance to participate in NASA’s return to the Moon with the Artemis program!
NASA is inviting people to submit their names to be included on a flash drive that will be sent along with Artemis I, an uncrewed test flight that kicks off the space agency’s plans to land the first woman and first person of color on the Moon.

Observers have been tracking a chunk of space junk, waiting for it to strike the Moon. It should’ve hit the far side of the Moon, and hopefully, orbiters will have images of the impact site, though that might take a while.
The origins of the junk are in dispute. Some say it’s a spent booster from a Chinese rocket. Others say it’s from a SpaceX rocket. So far, nobody is claiming it.

We know a ton about the inside of Earth. We know it has both an inner core and an outer core and that the churning and rotation create a protective magnetosphere that shields life from the Sun’s radiative power. It has a mantle, primarily solid but also home to magma. We know it has a crust, where we live, and plate tectonics that moves the continents around like playthings.
But what about Super-Earths? We know they’re out there; we’ve found them. What do we know about their insides? Earth’s structure, and its ability to support life, are shaped by the extreme pressure and density in its interior. The pressure and temperature inside Super-Earths are even more powerful. How does it shape these planets and affect their habitability?

Radar is finicky. It is extraordinarily useful for a multitude of tasks, but testing it for some particular tasks is complicated since almost everything interferes with it. That challenge is particularly acute when testing an antenna that is supposed to be used in space, which is why a team from the SENER engineering group in Spain decided to take a novel approach to testing the radar antenna the European Space Agency (ESA) plans to use for EnVision – they suspended it from a balloon.

The ongoing conflict in Ukraine has wide-reaching implications, not only in the geopolitical sphere but also outside of the atmosphere. On the International Space Station (ISS), Russians work alongside astronauts from other countries that are currently imposing economic and trade sanctions in an attempt to force their country to stop their invasion of their neighbor. It was only a matter of time before that conflict escalated to the point of arguments over the ISS, but this time an unlikely hero appeared to defend the interests of Western nations – Elon Musk.

We’ve all seen the gorgeous images and videos of coronal loops. They’re curved magnetic forms that force brightly glowing plasma to travel along their path. They arch up above the Sun, sometimes for thousands of kilometres, before reconnecting with the Sun again.
But a new study says that some of what we’re seeing aren’t loops at all. Instead, they’re a type of optical illusion. Do we know the Sun as well as we think we do?

Astronomers discovered the first exoplanets in 1992. They found a pair of them orbiting the pulsar PSR B1257+12 about 2300 light-years from the Sun. Two years later they discovered the third planet in the system.
Now a team of astronomers are trying to duplicate that feat by searching 800 known pulsars for exoplanets.

Artificial gravity remains the stuff of science fiction. But dealing with no gravity causes significant problems in many astronauts, ranging from bone deterioration to loss of sight. An alternative method that might eliminate some of these problems is “simulated gravity,” which uses a spinning structure to create centrifugal force that would have the same effect on the body as gravity would. Whether or not this would solve the problems caused by lack of gravity remains to be seen. Still, NASA seems keen on the idea – to the tune of a $600,000 NASA Institute for Advanced Concepts (NIAC) Phase II grant to a team from Carnegie Mellon University (CMU) and the University of Washington (UW) who is looking to develop a structure that can simulate full Earth gravity and be launched in a single rocket.

Who is excited to send a spacecraft to Europa? Every person I’ve talked to who is even remotely interested in planetary exploration is incredibly enthusiastic about the upcoming Europa Clipper mission to explore Jupiter’s icy moon. With strong evidence of a subsurface liquid ocean, Europa is considered by many to be the most likely place in our Solar System – besides Earth — which might harbor life. The many mysteries about this moon make it a compelling place to explore.

Earlier this year, the discovery of a potentially hazardous asteroid took astronomers on a roller coaster ride.
On January 6, 2022, astronomers at the Mount Lemmon Observatory in Arizona discovered an asteroid roughly 70-meters (230 ft) across. Based on their initial observations, it appeared this object — called ‘2022 AE1’ – could potentially hit Earth on its next pass, on July 4, 2023.
