The First U.S. Spacewalk – Gemini 4 Ed White made the United States' first spacewalk on June 3, 1965 during the Gemini 4 mission. The extra-vehicular activity (EVA) started at 19:45 UT (3:45 p.m. EDT) on the third orbit when White opened his hatch and used the hand-held manuevering oxygen-jet gun to push himself out of the capsule.

Space Shuttle Discovery is towed from the shuttle landing facility to the orbiter processing facility at Kennedy Space Center on April 20, 2010 in Cape Canaveral, Florida. Discovery's landing attempts at KSC were scrubbed yesterday due to unacceptable weather conditions. Discovery is returning from a successful mission to the International Space Station.

The launch of a rocket into space is projected on Dubai's Burj Khalifa on February 9, 2021 as the UAE's “Al-Amal” – Arabic for “Hope” – probe's to Mars carries out a tricky manoeuvre to enter the Red Planet's orbit. A tense half-hour today will determine the fate of “Hope”. If successful, the probe which is designed to reveal the secrets of Martian weather, will become the first of three spacecraft to arrive at the Red Planet this month.

“Space Exploration Technologies Corp. (SpaceX) is an American space transport company founded by PayPal co-founder Elon Musk. It has developed the Falcon 1 and Falcon 9 rockets, both of which are built with a goal of being reusable launch vehicles. SpaceX is also developing the Dragon spacecraft to be carried to orbit by Falcon 9 launch vehicles. SpaceX designs, tests and fabricates the majority of their components in-house, including the Merlin, Kestrel, and Draco rocket engines. In December 2010, SpaceX became the first private company to successfully launch, orbit and recover a spacecraft (a Dragon)”. – Wikipedia

SpaceX, the space transportation company built from scratch by visionary billionaire Elon Musk, has the grand goal of space travel evolution through the use of re-usable rockets. Its technology – which has proven its worth several times – can reduce the costs of space transportation to its fraction, making it a more affordable way of reaching orbit or traveling beyond.
