The Soviets developed a similar design known as the Buran , which also consisted of a reusable orbital vehicle, along with the Energia super rocket. This latter element consisted of an external fuel tank and four strap-on boosters. Following the disintegration of the Soviet Union in , the Buran program was canceled. Two of these were lost in operation - the Challenger exploded on launch in and the Columbia broke up on re-entry in - while the remaining three were retired in Between and , the Space Shuttle fleet conducted launches and was essential to the deployment of satellites, several orbiting observatories like the Hubble Space Telescope , and many of the components used to build the ISS.
These developments helped lay the groundwork for the modern era of space exploration, which is characterized by international cooperation, the search for more cost-effective methods of space exploration, and the dream of establishing far-reaching, sustainable human space exploration. One of the clearest indications that space exploration has become an international affair since the Apollo era is the way that more nations have been sending missions to the Moon.
The spacecraft also deployed the Hagoromo to gather more information from its lunar orbit, but the transmitter failed. Kaguya named for a moon-born princess in Japanese folklore. During the year and eight months that it orbited the Moon, the mission gathered vital data on the Moon's topography, chemical, and magnetic environment.
The mission also made the first optical observations of the famous Shackleton crater at the lunar south pole. Known for being permanently shaded, and for possibly containing large amounts of water ice, this crater is being considered by many space agencies as a possible location for a permanent Moonbase. This began in October of with the launch of Chandrayaan-1 , an uncrewed lunar orbiter. The probe was originally intended to orbit and map the Moon for two years but crashed on the surface after 10 months.
The mission also included the Moon Impact Probe, which struck the south pole of the Moon in a controlled manner on November 14th, , making India the fourth country to land on the lunar surface. The purpose of the probe was to eject material from beneath the surface for analysis.
Among other things, this revealed evidence for the presence of water in the lunar soil. On July 22nd, , the ISRO launched their second lunar exploration spacecraft Chandrayaan-2 , which is scheduled to deploy a lander and a rover to the lunar surface on September 7th.
This will make India the fourth nation to achieve a soft landing on the Moon. In , they launched the Chinese Lunar Exploration Program - aka. This program has consisted of a series of increasingly-sophisticated robotic missions exploring the Moon in preparation for an eventual crewed mission.
The program is designed to occur in three phases. For Phase I, two robotic spacecraft were to be sent to study the Moon from orbit. Phase II would entail soft landers and rovers landing on the surface to explore and conduct experiments. Phase III would involve additional landers and rovers that would conduct sample-return missions with Earth.
The fourth and final phase calls for the creation of a robotic research station near the Moon's south pole. The program's first lunar orbiter Chang'e 1 was launched in , which made China the fifth nation to successfully orbit the Moon and map its surface.
This was followed by the launch of the Chang'e 2 in , which mapped the Moon in greater detail. This concluded Phase I of the Chang'e program. This was followed by Phase II, which began with the Chang'e 3 lander in This mission deployed the Yutu 'Jade Rabbit' rover on the lunar surface, which explored the lunar surface and conducted ultra-violet astronomy experiments and studies of Earth's plasmasphere.
The Chang'e 4 lander, reached the far side of the Moon in January of The Yutu 2 rover was then deployed to explore the South Pole-Aitken Basin , a location that is thought to contain supplies of water ice and is considered a possible location for a lunar outpost.
The lander also carried the Lunar Micro Ecosystem LME experiment, a metal cylinder containing seeds and insect eggs designed to test the effects of lunar gravity on living creatures.
The orbiter component of the mission also tested the ability to relay communications from the far side of the Moon. These experiments are designed, in part, to determine whether long-term human missions to the Moon which include an outpost are possible. The third phase will conclude with another sample-return mission conducted by the Chang'e 5 lander and orbiter, which launched on Nov.
In February of , the first Israeli and privately-funded lunar mission Beresheet launched from Cape Canaveral, Florida, atop a Falcon 9 rocket. While the lander malfunctioned and crashed on the lunar surface, it managed to enter lunar orbit beforehand - a historic first for the nation. The achievements of these national space agencies have helped advance lunar exploration considerably.
In the future, the prospect of international collaborations between many or all of them will be key to taking lunar exploration to the next level. Addressing the fact that all missions since the Apollo era had been to Low-Earth Orbit, the focus of their efforts was on taking the next great leap. The following year, O'Keefe's successor, Michael D. Griffin , further refined these goals with the Exploration Systems Architecture Study , issued in November of This led to the creation of the Constellation Program , a three-step endeavor that envisioned the creation of a new class of CEV and a heavy-launch rocket that would allow for the "completion of the International Space Station", a "return to the Moon no later than ", and an eventual mission to Mars.
At the heart of the program was a new class of heavy-launch vehicle known as the Ares rocket family. This consisted of the Ares I , a two-stage rocket that would launch the Orion into space, and the Ares V that would launch heavy payloads. In February of , the program was canceled due to the changing budget environment in the wake of the Great Recession of Whereas the former would allow for missions to return to the Moon via a reusable orbital lander, the latter would allow for missions to deep-space destinations like Mars.
These efforts are now officially known as Project Artemis , named after the twin sister of Apollo in Greek mythology. Due to their expedited timetable, NASA now plans to execute their return to the Moon with three missions. The first mission Artemis I will be a test flight that will take an uncrewed Orion capsule around the Moon.
The United States would go on to complete six crewed missions to the moon that landed a total of 12 astronauts all men from to in a series of Apollo missions numbering up to Apollo Crewmen aboard the U. Iwo Jima, prime recovery ship for the Apollo 13 mission, hoist the Command Module aboard. Been there, done that. The lightweight unit folded up under the lunar landing module, ran on electric power and boasted its own onboard navigation system that communicated directly with mission control on Earth.
Apollo 15 astronauts drove 17 miles across the lunar surface collecting rocks from different geological formations. One of the Apollo 15 astronauts brought home an ancient hunk of anorthosite that was later determined to be 4. Apollo 15 signaled the beginning of longer and more extensive scientific inquiry on the moon during Apollo 16 and Launched on 2 January , the Soviet Union probe Luna 1 travelled to within almost miles of the Moon's surface in 34 hours. The mission's original objective was to land on the Moon, but the probe went too fast and ended up in orbit around the Moon, where it remains today.
The Apollo 11 mission in , crewed by three astronauts took four days, six hours and 45 minutes. Apollo 10 holds the record for the highest velocity reached by a crewed spacecraft at 24, miles per hour.
This passed the Moon in 8 hours and 35 minutes on its way to Pluto. However, the spacecraft didn't even slow down or approach lunar orbit. They landed in the Taurus-Littrow valley on 11 December and departed on 14 December. During this time, they explored the lunar surface for around seven hours each day, collecting samples and driving in a lunar rover vehicle.
They spent 22 hours on the Moon in total. Cernan's final words before lifting off were. A total of six flags have been planted on the Moon — one for each US Apollo landing. Unfortunately, Apollo 11's flag was too close to the landing module and was knocked over by the exhaust when the module launched again.
More recently, higher resolution images from the Lunar Reconnaissance Orbiter show that the other five remain standing. The flags were made of ordinary nylon, so they have all long since been bleached white by the Sun's UV radiation.
