Standing atop the mobile launcher, NASA’s Space Launch System (SLS) rocket and Orion spacecraft arrive at Launch Pad 39B at the agency’s Kennedy Space Center in Florida on March 18, 2022. The Artemis I stack was carried from the Vehicle Assembly Building to the pad – a 4.2-mile journey that took nearly 11 hours to complete – by the agency’s crawler-transporter 2 for a wet dress rehearsal ahead of the uncrewed launch. Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and the first person of color on the lunar surface, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

The Launch Pad tour stop at the Mississippi I-10 Welcome Center in Hancock County, Miss., is the point of origin for all tours of Stennis Space Center and StenniSphere. At the Launch Pad, visitors waiting to catch the shuttle buses are provided information and can see videos on StenniSphere exhibits and on the missions and programs of Stennis Space Center. StenniSphere is open free of charge from 9 a.m. to 5 p.m. daily, and buses depart from the Launch Pad to StenniSphere every 15 to 20 minutes.

Space Shuttle Endeavour paints the still-blue evening sky as it leaves Earth behind on its journey into space on mission STS-118. Liftoff from Launch Pad 39A was on time at 6:36 p.m. EDT. The mission is the 22nd shuttle flight to the International Space Station. It will continue space station construction by delivering a third starboard truss segment, S5, and other payloads such as the SPACEHAB module and the external stowage platform 3. The 11-day mission may be extended to as many as 14 depending on the test of the Station-to-Shuttle Power Transfer System that will allow the docked shuttle to draw electrical power from the station and extend its visits to the orbiting lab.

After successfully arriving at Kennedy Space Center’s Launch Complex 39B, Exploration Ground Systems’ mobile launcher is photographed at the pad surface on June 28, 2019. The mobile launcher began its final solo trek to the pad at midnight on June 27, departing from NASA’s Vehicle Assembly Building. The mobile launcher will remain at the pad over the summer, undergoing final testing and checkouts. Its next roll to the pad will be with the agency’s Space Launch System rocket and Orion in preparation for the launch of Artemis 1.

The engine service platform has been lowered and removed from the mobile launcher for Artemis I at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on Oct. 23, 2020. It is staged on the top of the pad. The nearly 400-foot-tall mobile launcher is at the pad while engineers with Exploration Ground Systems and Jacobs complete several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.

The SLS rocket and Orion are scheduled to launch no earlier than Aug. 29, 2022, at 8:33 a.m. EDT. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.

The nearly 400-foot-tall mobile launcher will remain at the pad while engineers with Exploration Ground Systems and Jacobs complete several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.

Space shuttle Atlantis (left) and space shuttle Endeavour are seen on Launch Pads 39A and 39B, respectively, at NASA's Kennedy Space Center in Florida. This is probably the final time two shuttles will be on launch pads at the same time with the space shuttle fleet set for retirement in 2010. Surrounding pad 39B are the lightning towers erected for NASA's Constellation Program, which will use the pad for Ares rocket launches. Endeavour will be prepared on the pad for liftoff in the unlikely event that a rescue mission is necessary following space shuttle Atlantis' launch on the STS-125 mission to service NASA's Hubble Space Telescope. After Atlantis is cleared to land, Endeavour will move to Launch Pad 39A for its upcoming STS-127 mission to the International Space Station, targeted to launch June 13. Original photo number is KSC-2009-2771.

Aviators, skydivers and other altitude-seeking enthusiasts flying out of Wanaka Airport, New Zealand, are double taking at a new topographical feature reminiscent of an alien crop circle. Rest assured, the nearly 2,000-foot (600-meter) diameter circle with a pie-shaped wedge on one side and spokes on the other is no extraterrestrial footprint and it’s definitely no hoax. It’s NASA’s newest launch pad for launching the agency’s most advanced high-altitude, heavy-lift scientific balloon: the super pressure balloon. The four spokes emanating from the center and toward the west, each nearly 1,000 feet (300 meters) long, align with magnetic compass directions at 240, 260, 290 and 320 degrees. On launch day, balloon flight experts from NASA’s Columbia Scientific Balloon Facility will assess meteorological data and determine if the conditions are suitable to support a launch opportunity. The new pad is the first major project in developing a long-term super pressure balloon launch site in Wanaka. Earlier in 2017, NASA signed a 10-year lease with the Queenstown Airport Corporation to conduct balloon operations from a newly acquired piece of land adjacent to the Wanaka Airport.

The rocket is adorned with the logo of the Sochi Olympic Organizing Committee and other related artwork to commemorate the launch of the Olympic torch with the crew for a four-day visit to the station. The torch will return to Earth with another trio of station residents on Nov. 11 and will be part of the torch relay that ends with the lighting of the flame at the Fisht Stadium in Sochi, Russia Feb. 7 to mark the opening of the 2014 Winter Olympics.

S75-32339 (28 Jan. 1974) --- A low-angle view of a launch pad at the Baikonur Cosmodrome in Kazakhstan showing the installation of a Soyuz spacecraft and its launch vehicle. The 49.3-meter-high (162 feet) space vehicle is composed of the three-stage booster, a three-module, two-man Soyuz spacecraft and a launch escape system. The weight of the space vehicle at launch is approximately 300,000 kilograms. The first stage vacuum thrust is about 1,000,400 newtons, the second stage is 956,500 newtons, and the third stage is 299,000 newtons.

NASA’s Artemis I Space Launch System and Orion spacecraft atop the mobile launcher on the pad at Launch Complex 39B at the agency’s Kennedy Space Center in Florida are reflected in the nearby waterway on Aug. 19, 2022. Launch of Artemis I is scheduled for no earlier than Aug. 29, 2022, at 8:33 a.m. EDT. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.
