- According to the National Aeronautics and Space Administration (NASA) on the 18th, a planet similar in size to Earth and estimated to have active volcanic eruptions has been discovered. It is believed that this planet, with its volcanic activity and atmosphere, may have water in the colder regions, which is considered essential for the emergence and sustainability of life forms.
The research team from the Institute for Research on Exoplanets (iREx) at the University of Montreal observed the planet called "d" in the LP 791-18 planetary system, a red dwarf star. The findings were published in the scientific journal 'Nature' on the 18th.
However, it is worth noting that the distance to this planet is approximately 90 light-years away.

Located 5,000 light-years away from Earth, the "Boomerang Nebula" is the coldest place in the universe. Resembling a butterfly bowtie, this nebula is also known as the "Butterfly Nebula." Its temperature measures at a chilling minus 272.12 degrees Celsius. The Boomerang Nebula was formed from gas expelled by a dying star, and the gas expansion speed approaches a staggering 200 km per second.
The hottest planet in the universe is "KELT-9b," situated 620 light-years away from Earth. This planet has a surface temperature of 4,327 degrees Celsius, which is nine times hotter than the surface temperature of Venus, the hottest planet in our solar system, at 460 degrees Celsius. Composed mainly of gas, this planet is similar to our solar system's Jupiter, with a mass 2.88 times that of Jupiter and a radius 1.89 times larger. 😆
- NASA's robotic rover, Perseverance, has discovered a rock band created by the strong currents of an ancient river in the delta region of Mars. Previously, Curiosity discovered sedimentary rocks with ripple marks created by waves in an ancient lake. The newly discovered rocks provide evidence of a fast and deep river. Perseverance is currently exploring the summit of the delta-shaped triangular area, which reaches a height of 250 meters. This area was first discovered years ago through a Mars reconnaissance orbiter under the name Skrinkle Haven. Scientists also believe that the sedimentary hill, Pinestand, was created by a fast and deep river. This area is estimated to have had very strong and fast currents, causing numerous rocks to move.
- The Russian government has agreed to continue its participation in the International Space Station (ISS) until at least 2028, after previously considering leaving the partnership after 2024. The other partners of the ISS, including NASA, the Canadian Space Agency, European Space Agency, and Japan Aerospace Exploration Agency, had already agreed to extend the station’s operations beyond 2024 to 2030. Yuri Borisov, head of Roscosmos, confirmed that Russia will support the station's extension to 2028 in letters to the other space agencies involved in the ISS. NASA Administrator Bill Nelson emphasized the need for the U.S.-Russian partnership to continue operating the station, despite technical issues and geopolitical tensions. 🛰️🚀🛰️🚀🛰️🚀
- SpaceX successfully launched the ViaSat-3 broadband satellite on a Falcon Heavy rocket on April 30th from NASA’s Kennedy Space Center in Florida after experiencing delays due to severe weather conditions. The rocket's side boosters separated from the core stage and were not recovered to improve the rocket’s performance. The primary payload, ViaSat-3 Americas, was deployed around 4 hours and 32 minutes after lift-off, followed by two rideshare payloads. The mission was previously scheduled for April 18 but was delayed for undisclosed reasons to April 26. However, severe weather on April 27 caused further delays. 🚀🚀🚀🚀🚀
- SpaceX has successfully launched the second pair of O3b mPower satellites for SES, a global satellite and terrestrial communications provider. The satellites will operate in medium Earth orbit (MEO) to bring next-generation broadband constellations online. The launch was postponed due to bad weather but later successfully took off from Cape Canaveral Space Force Station in Florida on a Falcon 9 rocket. The Falcon 9’s first-stage booster also successfully landed on a drone ship in the Atlantic Ocean to be reused. SES confirms that the satellites have successfully made contact and will take a few more months to reach their final positions independently using onboard electric propulsion. SpaceX is scheduled to launch another pair of satellites in late June to help SES begin commercial O3b mPower service in Q3 of this year. The O3b mPower system has 11 satellites made by Boeing, all of which have SpaceX launch contracts. SES says only six satellites are needed to start providing services that promise ten times the processing capacity of the current MEO constellation.
Mars, here we come! Go SpaceX 🚀🛸🛰
- Elon Musk's space company SpaceX has secured a new rocket launch site.
According to the US Space Force on the 25th local time, the commander of the Vandenberg Space Force Base in California approved SpaceX's lease of the Space Launch Complex 6 (SLC-6) launch site on the 21st.
As a result, SpaceX's rocket launch sites have increased to a total of five, including the Cape Canaveral Space Force Station in Florida, the Kennedy Space Center launch site of NASA, the in-house launch site "Starbase" in southern Texas, and the existing launch site SLC-4E at the Vandenberg Space Force Base.
Elon Musk has announced a goal of 100 rocket launches this year. This is a goal that must be achieved by launching about one rocket every three or four days. It is somewhat questionable whether Musk has announced a feasible plan, but I want to support his passion.🚀🚀🚀🚀🚀
- Fish and Wildlife Service documents damage from Starship launch

- Northrop Grumman developing military communications satellite for 2025 launch
WASHINGTON — Northrop Grumman is developing a geostationary communications satellite that will compete against a Boeing design in a military procurement estimated to be worth $2.4 billion.
Boeing and Northrop Grumman were selected in 2020 by the U.S. Space Force to develop Protected Tactical Satcom prototype payloads, known as PTS. Both payloads passed government design reviews and were cleared for on-orbit demonstrations planned in 2025.

- Report recommends allowing “learning period” for commercial human spaceflight safety regulations to expire
WASHINGTON — A new report recommends that current restrictions on the Federal Aviation Administration’s ability to regulate safety for people flying on commercial spacecraft be allowed to expire later this year.
The report by the RAND Corporation, prepared for Congress and released April 3, concluded that despite limited progress on establishing voluntary industry safety standards, the FAA and industry were now ready to start the process of developing formal safety standards for those participating in commercial spaceflight.

- Canada proposes to develop robotic lunar rover for Artemis
WASHINGTON — As Canada celebrates its first astronaut to go to the moon, it is starting a new project that could eventually enable a Canadian to walk on the lunar surface.
Canadian astronaut Jeremy Hansen is among the members of the Artemis 2 crew announced April 3. Hansen, who will be making his first spaceflight, is slated to be the first non-American to travel to the vicinity of the moon when the mission launches as soon as late 2024.
