Thin Flat Lenses Could Unleash a Revolution in Space Telescopes
Thanks to the laws of physics, there are two basic rules about telescopes. The first is that the bigger your primary lens or mirror, the higher the resolution of your telescope. The second is that lenses and mirrors have to be curved to focus light into an image. So, if you want a space telescope sensitive enough to see the atmospheres of distant exoplanets, Your telescope is going to need a large curved mirror or lens. But neither of these things is technically true, as a newly proposed telescope design demonstrates.
China to launch moon astronauts' new spacecraft for 1st time in 2027 or 2028
China is planning to launch a next-generation crewed spacecraft around 2027 that will be capable of carrying astronauts to the moon and even beyond.
San Diego Comic-Con 2023: The space fan's ultimate guide

Satellite will die by fire as 1st-of-its-kind operation sends it plummeting down to Earth
Scientists will attempt a first-of-its-kind guided safe reentry to Earth's atmosphere with the European Space Agency wind satellite Aeolus as it heads home at increasing speed.
Hubble Space Telescope
The Hubble Space Telescope (HST) is one of the most iconic and influential telescopes ever launched into space. Operated by NASA and the European Space Agency (ESA), Hubble was launched on April 24, 1990, and remains in operation to this day. Here are some key facts about the Hubble Space Telescope:
Artemis 2 moon astronaut explains risk of flying NASA's supersonic training jet
Fighter pilot Jeremy Hansen, a Canadian astronaut on the Artemis 2 mission, talks about how the T-38 supersonic fleet 'can kill you' and why that's important for space training.
DART Impact Ejected 37 Giant Boulders from Asteroid Dimorphos’ Surface
When the DART (Double Asteroid Redirection Test) spacecraft intentionally slammed into asteroid moonlet Dimorphos on September 26, 2022, telescopes around the world and those in space watched as it happened, and continued to monitor the aftermath.
Most Americans expect routine space tourism by 2073, but few would actually try it: report
A Pew Research Center report reveals more than half of Americans expects to have access to space, but barely a third would be willing to make the trip themselves.
Strange two-faced dying star 'Janus' baffles scientists in cosmic oddity
While routinely scanning the sky for the burnt-out remnants of dying stars, scientists stumbled upon a strange cosmic signal.
Hubble sees boulders escaping from asteroid Dimorphos
Astronomers taking advantage of the NASA/ESA Hubble Space Telescope’s extraordinary sensitivity have discovered a swarm of boulders that were possibly shaken off the asteroid Dimorphos when NASA deliberately slammed the half-tonne DART impactor spacecraft into Dimorphos at approximately 22 500 km per hour. DART intentionally impacted Dimorphos on 26 September 2022, slightly changing the trajectory of its orbit around the larger asteroid Didymos.
Threats From Above Lead the List of Space Concerns in New Survey
Sending astronauts to the moon is OK — but more Americans think NASA should instead put a high priority on monitoring outer space for asteroids and other objects that could pose a threat to Earth, according to the Pew Research Center’s latest survey focusing on Americans’ perspectives on space policy.

Does Beaming Power in Space Make Sense at the Moon?
Space-based solar power (SBSP) is considered one of the most promising technologies for addressing Climate Change. The concept calls for satellites in Low Earth Orbit (LEO) to collect power without interruption and beam it to receiving stations on Earth. This technology circumvents the main limiting factor of solar energy, which is how it is subject to the planet’s diurnal cycle and weather. While the prospect of SBSP has been considered promising for decades, it’s only in recent years that it has become practical, thanks to the declining costs of sending payloads to space.
