Both the European Space Agency and NASA are planning to test even more sensitive sensors on future moon missions to try and hone in on satellite signals. If they can truly connect with sats back home, we could get closer to achieving autonomous moon travel. But eventually that won’t be enough. To help direct humans on the lunar surface, we’re going to need a fleet of satellites specifically around the moon. NASA calls its project LunaNet, and it’s part of the Gateway space station, which is the culmination of America’s plan to return to the moon. It needs to be designed to play well with ESA technology and, eventually, will be the source of high-speed internet on the moon.

Artemis I launched back in November, rounded the moon just 81 miles above the lunar surface and touched down Earth-side in December. Artemis II, which will carry astronauts around the moon in a similar trajectory, is slated to launch in late 2024, according to Space.com. Artemis III, which will be humanity’s first boots on the moon since 1972, could launch as early as 2025.

The company almost doubled its launch record set the previous year. This year, it will likely break new ground with Starship.

SpaceX’s first mission of 2023 launched a massive 114 satellites into orbit. The Falcon 9 rideshare mission, called Transporter-6, launched at 10:56 a.m. EST (1456 GMT) from Cape Canaveral Space Force Station in Florida.

The new mission kickstarts what is set to be a massive year for SpaceX as the company readies for the orbital launch of its next-generation Starship rocket.

It also follows on from what was a record-breaking year for SpaceX in 2022, with the company almost doubling its previous launch record.

This month, NASA launched a new Earth-monitoring satellite that will observe fresh water systems across the planet. Now, the satellite has unfurled in space ready to begin science operations, and NASA has shared a video showing the unfolding process.

Named the Surface Water and Ocean Topography (SWOT) satellite, it had been folded up to fit inside the SpaceX Falcon 9 rocket which launched it from Vandenberg Space Force Base in California on December 16. Once the satellite reached space, it had to deploy its solar panel arrays, then unfold its mast and antenna panels. While deploying the solar panel arrays was a quick process, taking place shortly after launch, the unfolding of the antennae was much more involved and took four days.

As the SWOT satellite has a camera at the end of its long master, used for its Ka-band Radar Interferometer (KaRIn) instrument, these cameras were able to capture the unfolding process on video. This instrument is a new type of interferometer that will be able to see the depth of fresh water bodies such as lakes and rivers by using radar pulses. It sends two radar pulses down to the surface with a slight offset, allowing researchers to see the depth of these features. This is possible because of the wide spread of its two antennae, spaced 10 meters apart.

Alpha Centauri, here we come.

However, while technology has indeed advanced a long way since the 1940s, it still seems like we are still a long way from having a fully functional von Neumann machine. That is unless you turn to biology. Even simple biological systems can perform absolutely mind-blowing feats of chemical synthesis. And there are few people in the world today who know that better than George Church. The geneticist from Harvard has been at the forefront of a revolution in the biological sciences over the last 30 years. Now, he’s published a new paper in Astrobiology musing about how biology could aid in creating a pico-scale system that could potentially explore other star systems at next to no cost.

“Pico-scale” in this context means weighing on the order of one pico-gram. Since the smallest operational satellite ever created so far weighed a mere 33 grams, scaling that down to 10–12 times that size might sound ambitious. But that’s precisely what biological systems could potentially do.

A typical bacteria weighs right around one pico-gram. And with sufficiently advanced genetic modification, bacteria can do anything from processing toxic waste to emitting light. Therefore, Dr. Church thinks they might make an excellent interstellar exploration tool.

The Surface Water and Ocean Topography (SWOT) satellite launched into Earth orbit on Friday, Dec. 16, from Vandenberg Space Force Base in central California, and engineers are working to prepare the mission to begin measuring the height of water on over 90% of Earth’s surface, providing a high-definition survey of our planet’s water for the first time.

But before it can do that, the satellite would need to unfold its large mast and antenna panels (see above) after successfully deploying the solar panel arrays that power the spacecraft. The mission monitors and controls the satellite using telemetry data, but it also equipped spacecraft with four customized commercial cameras to record the action.

The fully deployed shortly after launch, taking about 10 minutes.

India’s space program is still in its early stages but has been making global headlines in recent years after ISRO’s launch vehicle launched a record-breaking 104 satellites in one go a few years ago. More recently, a private space tech company test-fired the world’s first 3D-printed rocket engine, which has a turnaround of just four days.

The next phase of the country’s space story includes human space flight, which was announced in 2018 and expected to be launched this year, coinciding with the 75th year of Indian independence. However, the COVID-19 pandemic threw a spanner in the works delaying the project by two years.

SpaceX launched the first batch of a new generation of Starlink satellites into orbit early Wednesday (Dec. 28) and nailed a rocket landing at sea to mark a record 60th flight of the year.

A Falcon 9 rocket topped with 54 upgraded Starlink internet satellites — the first generation 2 (Gen2) versions of the SpaceX fleet — lit up the predawn sky with a smooth launch at 4:34 a.m. EST (0934 GMT) from the Cape Canaveral Space Force Station in Florida.

Dec 26 (Reuters) — SpaceX Chief Executive Elon Musk said on Monday that the company is now close to having 100 active Starlinks, the firm’s satellite internet service, in Iran, three months after he tweeted he would activate the service there amid protests around the Islamic country.

Musk said, “approaching 100 starlinks active in Iran”, in a tweet on Monday.

The billionaire had said in September that he would activate Starlink in Iran as part of a U.S.-backed effort “to advance internet freedom and the free flow of information” to Iranians.
