Despite great disappointment among researchers and space tech enthusiasts alike, NASA has made the bold decision to cancel the much anticipated Volatiles Investigating Polar Exploration Rover (VIPER) project earlier this month. The rover was initially set to launch sometime between 2024 and 2025, but NASA has chosen to terminate the project in its entirety, resulting in a significant amount of frustration among invested parties, as well as many questions regarding the reasons behind this monumental decision.

VIPER was intended to help scientists conduct important research into the availability and accessibility of water on the moon by attempting to source ice at the moon鈥檚 south pole. This endeavour formed part of a global attempt to assess the availability of water in space to try and start answering questions about the potential for life away from Earth.

Unsurprisingly, given the objectives of the VIPER project, the news of its discontinuation has been met with shock and despondency from those who have been following the project closely. In addition, many have expressed scepticism and concern over the $450 million that has already been invested in NASA鈥檚 research, especially considering the fact that they鈥檝e already, supposedly, completed the assembly of the actual rover, as well as the installation of its technological instruments.听

So, why did NASA cancel their much anticipated VIPER project, and what does this mean for the future of NASA鈥檚 research into the presence of ice and water on the moon?

Why Did NASA Cancel Their VIPER Project?听

In response to a flurry of questions about the sudden and harsh end of VIPER, NASA has stated that the decision was made in light of some very significant cost increases associated with the project as well as several delays of the launch date. In addition, they鈥檝e noted that according to their calculations and predictions, they expect costs associated with the VIPER project to continue to rise in the future in a way that is unsustainable.听

In 2022, the launch date was postponed from 2023 to late 2024, showing that the strain experienced by NASA doesn鈥檛 seem to be particularly sudden. The 2023 launch delay was purportedly due to a need to conduct more preflight testing than they鈥檇 been able to accomplish by their deadline, and since then, NASA鈥檚 reasoning for additional delays has included, among other things, supposed supply chain issues.听

The reason that the potential for a consistent increase in costs associated with VIPER has become detrimental to its existence is that it supposedly jeopardises other projects too. That is, NASA鈥檚 other Commercial Lunar Payload Services (CLPS) that research the surface of the moon are also expected to become threatened by the financial issue faced by VIPER.听

Ultimately, it was NASA鈥檚 decision that this threat was far too great to jeopardise the future of NASA鈥檚 CLPS altogether, resulting in the unfortunate and disappointing premature termination of VIPER.听
 

In response to these questions, representatives from the organisation have expressed that the rover itself will be disassembled and its instruments will be kept for future lunar missions. NASA has also stated that there is potential for US industry members and other international partners to make use of the rover system before it鈥檚 disassembled, ensuring that it doesn鈥檛 go to waste.

In an interesting turn of events, Griffin Mission One, the mission that was supposed to be responsible for launching VIPER, will go ahead as planned at some point after 2025 as part of a flight demonstration of the Griffin lander and its engines, rather than the actual launch of the rover.

So, What鈥檚 Next for NASA鈥檚 Exploration of the Moon for the Benefit of Humanity?听

The good news, according to NASA, is that the cancellation of VIPER is merely a setback, and it won鈥檛 stop their pursuit of attempting to locate ice on the moon. They鈥檝e made it very clear that in addition to the fact that Griffin Mission One going ahead with its flight, the agency remains committed to attempting to accomplish the goals initially set out by VIPER. According to NASA, the verification of the presence of ice at the lunar south pole is still a top priority. On top of that, NASA is also going ahead with other scheduled CLPS deliveries.

Overall, Nicola Fox, an associate administrator for NASA鈥檚 Science Mission Directorate, has stated that NASA is 鈥渃ommitted to studying and exploring the Moon for the benefit of humanity through the CLPS programme鈥�. Fox also noted that their move forward involves plenty of other missions and projects in the works for CLPS. In addition to this, they鈥檙e also actively making use of research conducted by VIPER, as well as technology developed for the project, ensuring that the time, effort and money invested in the project doesn鈥檛 go to waste.听

Regardless of having to make this difficult decision to terminate VIPER, NASA doesn鈥檛 seem to intend to stop moving forward in their pursuit of advanced lunar research – this is merely a bump in the road, and they鈥檙e already working on paving a new path forward.听

Although the decision to put an end to VIPER is disappointing, NASA鈥檚 firm stance on continuing CLPS projects in the broader context of their lunar exploration and research is a promising indication that the future still holds great potential for exciting discoveries on the moon.
