Space exploration has granted us the opportunity to uncover the wonders of the cosmos. Yet, as we venture further, new mysteries emerge surrounding spacecraft, renowned astronauts, and unexplained phenomena. Some mysteries have been resolved or reasonably clarified, while others remain puzzling. Here, we delve into 10 of the most captivating space travel-related enigmas.
10. Space Object 2014-28E
In 2014, Russia sent three military satellites into space using the same rocket, a fairly routine event. However, what set this launch apart was the discovery that an object, initially thought to be debris, began to maneuver through space. NASA designated the object as 2014-28E, and it positioned itself near the upper stage of the rocket that had carried it. Subsequently, Russia updated their mission details to include a fourth satellite.
This satellite might be a test platform for interceptor satellites, designed to approach and either spy on or potentially damage other satellites in space, possibly through ramming or other means. While the United States and China had previously tested such systems before the launch of Object 2014-28E, Russia has remained tight-lipped about the satellite's purpose, never formally acknowledging its existence, unlike the US and China with their own tests. Speculation suggests the test could be a continuation of the Soviet Union's Istrebitel Sputnik anti-satellite program.
9. Military Shuttle Missions
The design specifications for the Space Shuttle were significantly influenced by the US Air Force, which aimed to use the shuttle to deploy large military satellites into orbit and return substantial payloads to Earth. The Shuttle's distinctive delta-wing design was a direct result of military needs, with the Air Force playing a pivotal role in supporting the Shuttle program. Between 1982 and 1992, the military launched 11 Space Shuttle missions, carrying everything from military communication satellites to covert spy satellites. While many of the more routine missions involving communication satellites have since been declassified, many others remain classified, with the details still shrouded in mystery.
Astronauts involved in these missions have remained tight-lipped, though a few fragments of information have surfaced over time. For instance, the classified mission STS-27 has now been confirmed to have used the shuttle’s robotic arm. Other tidbits have emerged: In 2001, just before NASA's official 100th spacewalk, astronauts were informed that they were actually performing the 101st spacewalk, subtly hinting that a secret spacewalk had taken place during one of the military shuttle missions.
8. Secret Military Mission Patches
In the 1960s, during the Gemini program, astronauts established a tradition of designing their own mission patches. The National Reconnaissance Office (NRO), the U.S. agency in charge of overseeing spy satellites, adopted a similar practice. For every mission, despite its secretive nature, a unique mission patch is created.
Although these mission patches were publicly available for years, they largely went unnoticed until the launch of NROL-11 in 2000. The NROL-11 patch inadvertently revealed sensitive details about the mission, allowing a civilian astronomer to predict the satellite's orbit based solely on clues from the patch. It was also deduced that the satellite's launch was intended to replace an older, nonfunctional one.
When the story became public, the patches were met with widespread attention, but rather than opting for further classification, the NRO responded by designing increasingly creative patches—each still concealing hidden clues. (NROL-49’s patch is shown above.) For example, two stars on a patch with a spacecraft may hint at a pair of satellites that monitor enemy naval vessels, while dragon wings on another patch could symbolize high-altitude signals intelligence satellites. However, the true meaning remains speculative, and many of these patches' intriguing clues are still veiled in secrecy.
7. The Crash Site of Apollo 16’s Third Stage
The third and final stage of the enormous Saturn V rockets, known as the S-IVB, was responsible for propelling the Apollo astronauts from low Earth orbit to the Moon. After Apollo 12, all subsequent S-IVB stages were intentionally crashed into the Moon. These crashes allowed scientists to study the internal structure of the Moon through the energy released by the impacts. All the impact sites were tracked successfully, except for Apollo 16, where NASA lost contact with the S-IVB stage before it collided with the lunar surface.
For decades, the location of Apollo 16’s S-IVB impact site remained a mystery, despite NASA probes successfully identifying the impact sites of all other Apollo missions' S-IVB stages. However, in late 2015, after further analysis of photographs, scientists finally pinpointed the site. The reason it had eluded discovery for so long was because it had crashed 30 kilometers (19 miles) away from the anticipated impact location.
6. The Pioneer Anomaly
Launched in 1972 and 1973, the Pioneer 10 and 11 probes were the first to venture into the outer solar system, passing through the asteroid belt and making flybys of Jupiter and Saturn. Their trajectory was set to carry them beyond the solar system. However, about a decade after their launch, scientists noticed the probes were gradually slowing down. Initially, they believed this was caused by propellant leakage, but by 1998, the slowing continued, suggesting a need for a new theory of physics that contradicted Einstein's ideas to explain the probes' changes in velocity.
The mystery lingered until the 2000s when a team of scientists revisited decades-old data from the probes and painstakingly recreated software models of the spacecraft from their original blueprints. By examining the Pioneers' thermal properties to determine if any part of the spacecraft was emitting heat in a way that could be causing the slowdown, they concluded that the paint on the Pioneers’ radioisotope electric generators was responsible for the change in velocity.
5. The Prowler Satellite
In 1990, the Space Shuttle Atlantis embarked on a covert military mission, STS-38. Initially, its payload was described as a signals intelligence satellite intended for geosynchronous orbit, launched by a two-part upper stage. However, a single declassified photo (shown above) revealing Atlantis's aft structure during the mission contradicted this description, leading to questions about the true nature of the payload and what kind of satellite(s) Atlantis was actually carrying.
The US military’s satellite catalog lists two objects launched into geosynchronous orbit during STS-38. In 1999, reports began to surface suggesting that two satellites were in fact launched—a military communications satellite and a highly classified stealth satellite known as the Prowler. The Prowler was believed to have maneuvered within geosynchronous orbit, spying on communication satellites while utilizing stealth technology to avoid detection.
Although there is considerable circumstantial evidence supporting the existence of the Prowler, the US government has never officially acknowledged its existence. As a result, the true details of STS-38 and the Prowler remain concealed under a veil of secrecy.
4. Beagle 2
The Beagle 2 Mars lander, the first British space probe ever built, was carried to Mars aboard the European Space Agency’s Mars Express orbiter in 2003. Unfortunately, after detaching from Mars Express, communication with Beagle 2 was lost. Several theories emerged to explain the silence, most attributing it to issues with the landing system, which had experienced numerous complications. Most scientists presumed that the probe had crashed onto the Martian surface and that was the end of its mission.
In January 2015, NASA's space probe located Beagle 2 intact on the Martian surface. The lander had successfully touched down, but its antenna failed to deploy, preventing it from communicating with Earth or receiving commands. This discovery brought much-needed closure to Beagle 2's scientific team, who had spent almost a decade searching for the lander, meticulously analyzing images taken by NASA and European space probes.
3. Apollo BP-1227
Apollo BP-1227 was a mock-up of the Apollo capsule used by US Navy ships to simulate the recovery of Apollo astronauts. In 1970, it was reportedly lost at sea off the coast of Great Britain during one of its operations. However, a Soviet ship in the vicinity may have intercepted it. Eventually, the mock-up found its way back into the hands of the United States.
In late 1970, the US icebreaker Southwind visited the Soviet port of Murmansk, where Soviet officials unveiled an Apollo capsule, later identified as BP-1227. The Soviets claimed the capsule had been recovered by a Soviet fishing boat off Spain's eastern coast, and in a grand ceremony, they transferred it back to the crew of the Southwind. The icebreaker then returned it to the United States, where it was handed back to NASA and eventually displayed.
The details surrounding BP-1227's journey between its loss at sea and its transfer to the Southwind remain shrouded in mystery.
2. The Death of Yuri Gagarin
In 1968, just seven years after Yuri Gagarin’s pioneering spaceflight in 1961, he tragically died in a training jet crash along with his flight instructor. The official Soviet investigation claimed Gagarin had attempted to avoid a bird, causing the aircraft to spiral out of control. However, this explanation has been disputed by everyone from his fellow cosmonauts to the KGB, who launched their own covert investigation into Gagarin’s death.
Alexei Leonov, who was nearby during the crash, reported hearing two sonic booms just seconds apart. Leonov also saw an Su-15 fighter jet, which was undergoing testing that day, flying lower than permitted. The official inquiry didn’t mention the Su-15, but Leonov suspects the pilot of that jet may have unintentionally caused Gagarin’s plane to enter a spin by flying too close.
The KGB, however, speculated that flight controllers might have contributed to Gagarin’s death by providing inaccurate weather data. Various other theories have been proposed, including sabotage or the suggestion that Gagarin may have been intoxicated when piloting his aircraft. The true cause of the crash remains a mystery.
1. The Crash of Object WT1190F
WT1190F, a mysterious object that once orbited Earth, was first observed in 2013, but it wasn’t officially catalogued until October 2015. Analysis of its trajectory revealed that it was headed for a collision with Earth. Further investigation revealed that it was not a naturally occurring asteroid. With a density just one-tenth that of water, WT1190F was most likely the upper stage of a rocket that had launched a space probe, though which probe it carried is still unknown. Some conspiracy theorists have claimed the object could be evidence of extraterrestrial life.
On November 13, 2015, WT1190F reentered Earth's atmosphere over the East Indian Ocean, providing scientists with an opportunity to study how artificial objects behave during reentry. Initial analysis suggested that the object could be the upper stage of the Lunar Surveyor probe, although experts remain uncertain. More data on WT1190F's trajectory is needed before any definitive conclusions can be made.
