SpaceX successfully launched the Crew-8 mission in collaboration with NASA on Sunday from the Kennedy Space Center in Florida. NASA and SpaceX launched a crew of four to the International Space Station in the Dragon spacecraft, marking the third attempt after they cancelled it twice due to poor weather conditions. The launch marked SpaceX's eighth crew rotation mission in the ISS with NASA's Commercial Crew Program. NASA astronauts involved in the mission are Commander Mattew Dominick, Pilot Michael Barratt, and Mission Specialists Jeanette Epps and Alexander Grebenkin, a Russian Roscosmos cosmonaut. Barratt would be making his third visit to the ISS with this mission. The four-member crew will return to Earth in the fall. They will spend six months at the ISS. SpaceX used their "reusable, two-stage rocket" Falcon 9 to launch the Dragon spacecraft. After detaching from Dragon, the Falcon 9 will land at Cape Canaveral Space Force Station.

ISS Program Manager Joel Montalbano stated at a Crew-8 mission briefing, "It's not an impact to Crew-8, but I didn't want anybody to be surprised." At 10:53 pm on Sunday, the mission lifted off after the engineers concluded that a small crack on the hatch seal wouldn't be an issue in launching the mission. The mission crew members cheered on the ground as the first-stage booster separated from Dragon and the spacecraft moved towards space. The crew will perform over 200 science experiments at the ISS, often referred to as a "floating laboratory." These experiments are a part of the long-term mission to prepare humanity for long-term stays in space. One such experiment is taking stem cells to space to study their effects on degenerative disease. Another involves observing the cellular impact of microgravity and ultraviolet radiation on plants. Furthermore, the crew will test pressure cuffs on legs to check whether they help relieve health problems. Astronauts will also see whether microalgae can help remove carbon dioxide from the air, providing food and oxygen for them. In the last year, SpaceX undertook almost a hundred launches. Their next launch is the Transporter-10 mission. SpaceX's official website says, "Transporter-10 is SpaceX's 10th dedicated smallsat rideshare mission. There will be 53 payloads on this flight, including CubeSats, MicroSats, and a hosted payload." (With inputs from agencies)

SpaceX, NASA launch Crew-8 astronaut mission to International Space Station

Mars is a perfect inspiration for science fiction stories. It's recognisable and well-studied, yet it's also unique and far enough away to entice fantastical experiences.

Mars is a perfect inspiration for science fiction stories. It's recognisable and well-studied, yet it's also unique and far enough away to entice fantastical experiences. Hollywood has created several science fiction movies about a man going to Mars. The Martian is the closest movie that attempts to explain the problems humans will have while exploring the red planet. However, it ignores space radiation, the most challenging subject that astronauts face. Chandrayaan-3 has landed on the moon, and people are already excited about India's upcoming missions. Among the ideas, the mission to send a man to Mars remains on the top.

NASA also launched Perseverance, a small robotic helicopter Ingenuity, and associated delivery systems as part of NASA's Mars Exploration Program. While India and several other nations are working on various projects around Mars, no one has been able to send a human to the red planet. SpaceX CEO Elon Musk claims he will transport 1 million people to Mars by 2050. However, NASA scientist Dr Michelle Thaller explained that with the current technology, it is impossible to protect the astronauts travelling to Mars because the radiation from the solar flares and coronal mass ejections (CME) will kill human beings long before they reach.

However, it expands multifold when a solar flare erupts on the Sun or a CME sweeps over an area in space. A recent discovery found a correlation between the dying clouds of Neptune and rising solar activity. If the Sun can impact Neptune, the farthest planet in our solar system, it can affect a spacecraft between Earth and Mars, Dr Thaller told The US Sun. The radiation can cause radiation poisoning, various types of cancer, degenerative and genetic disorders, and even death. NASA astronaut Stan Love told The US Sun that there's simply no chance of creating a human colony on Mars by 2050 until we discover a new technology that can protect us against deadly radiation.

It's nearly impossible to send manned mission to Mars, NASA scientist explains why

The Shenzhou-16 manned mission is scheduled to launch tomorrow at 9:30 a.m. Beijing time. This will be the first manned space mission in which a member of the crew is a civilian from the Chinese space business rather than from the military.
