SpaceX is preparing for a possible launch of its prototype interplanetary Starship rocket from the company's facility in south Texas on Monday afternoon.
The company is hoping to finally perform a successful testflight after the last three attempts ended in spectacular explosions.
"I have ordered the closure of Boca Chica Beach and Hwy 4 for the purpose of protecting public health and safety during SpaceX space flight activities on March 29," Cameron County Judge Eddie Trevino Jr said in a statement.
SpaceX founder Elon Musk also tweeted on Sunday about the "Possible Starship flight tomorrow afternoon.
Corridor test of Proba-3’s formation flying sensors

The longest corridor in ESA’s largest establishment was turned into a test site for one of the Agency’s most ambitious future missions, Proba-3. The two satellites making up this mission will line up so that one casts a shadow onto the other, revealing inner regions of the Sun’s ghostly atmosphere. But such precision formation flying will only be possible through a vision-based sensor system allowing one satellite to lock onto the other.

The second European Service Module that will power the Orion spacecraft on a crewed flyby of the moon is fitted with a special engine at Airbus facilities in Germany.
This engine belonged to Space Shuttle Atlantis, and is one of five refurbished engines to be paired with the first five European Service Modules. Technicians carefully install the engine in Airbus' cleanroom.
ESM is the powerhouse of NASA's Orion spacecraft. It will provide critical functions such as the propulsion system to get astronauts to the moon, and the consumables astronauts need to stay alive.
ESM-2 will fuel the crewed Orion spacecraft during a flyby of the moon for Artemis 2 and is currently undergoing integration and other testing in Europe before it is delivered to NASA this summer.
Meanwhile in the United States, the first European Service Module is making its way to the launch pad as part of the Orion spacecraft for the Artemis 1 mission test flight later this year. Next stop is fuelling, due to take place next week.
ESM is ESA's contribution to NASA's Artemis program and includes involvement from 10 European nations.
Exploring the moon's shadowed regions using beamed energy

In less than three years, astronauts will return to the moon for the first time since the Apollo Era. As part of the Artemis Program, the purpose is not only to send crewed missions back to the lunar surface to explore and collect samples. This time around, there's also the goal of establishing vital infrastructure (like the Lunar Gateway and a Base Camp) that will allow for "sustained lunar exploration."
A key requirement for this ambitious plan is the provision of power, which can be difficult in regions like the South Pole-Aitken Basin—a cratered region that is permanently-shadowed. To address this, a researcher from the NASA Langley Research Center named Charles Taylor has proposed a novel concept known as "Light Bender." Using telescope optics, this system would to capture and distribute sunlight on the moon.
The Light Bender concept was one of 16 proposals that were selected for Phase I of the 2021 NASA Innovative Advanced Concepts (NIAC) program, which is overseen by NASA's Space Technology Mission Directorate (STMD). As with previous NIAC submissions, those proposals that were selected represent a broad range of innovative ideas that could help advance NASA's space exploration goals.

Climate change is having an undeniable influence on coastal areas. A substantial proportion of the world’s sandy coastlines are already eroding owing to increased storm surges, flooding and sea level rise. With our coastal environments in constant change, Earth observation satellites are being used to better strengthen our knowledge of changing coastlines.

Scientists have long known that certain ingredients are needed to support life, especially water and key organic chemicals like carbon. In recent years, both ingredients have been found on giant asteroids and other celestial bodies.
