Space, the final frontier. Throughout history, the expanse that exists beyond Earth has captivated people all over the world, with space exploration continuing to take giant leaps forward since Apollo 11 first landed on the moon.Now, outer space has peaked Wall Street’s interest. Given the high levels of private funding and advances in technology, the pros argue there could be major implications should space become more accessible and less expensive to reach. To this end, new markets such as satellite broadband, high-speed product delivery, reusable rockets and human space travel are emerging.Speaking to the potential opportunity, according to a recent KPMG report, by 2030, the global space industry could reach $600 billion, with it currently worth $350 billion. Bearing this in mind, we used TipRanks’ database to zero in on two space stocks reaching for the stars, so says the Street. Boasting the analyst community’s full support, both tickers have received a “Strong Buy” consensus rating. Virgin Galactic Holdings (SPCE)By offering high-speed point-to-point travel, Virgin Galactic wants to commercialize space travel and revolutionize commercial flight. Given the significant backlog of demand for commercial spaceflight, several members of the Street have high hopes for this space stock.Representing Cowen, analyst Oliver Chen sees SPCE as “uniquely positioned to benefit from the growing consumer interest toward luxury experiences, especially among high-net-worth individuals.” He added, “We believe a substantial growth opportunity lies ahead with the commercial spaceflight business, which already has ~600 reservations, and the development of high-speed point-to-point travel.”Looking at the market opportunity, Chen estimates that this part of the business could push SPCE’s top-line to $1 billion-plus by 2030, growing at a 60%-plus CAGR (2021-2030), with an EBITDA margin of 46%. According to the analyst, there’s a total addressable market (TAM) for commercial spaceflight (suborbital) of roughly 2.4 million individuals with a net worth of $5 million-plus globally.On top of this, SPCE could use its technology to develop additional revenue streams such as high-speed P2P commercial air travel. The development of hypersonic aircrafts would make 85% of the global network pairs accessible in a one-day trip. In addition, the analyst thinks the high-speed P2P opportunity could yield a TAM of $985 billion by 2050, and SPCE's market share could clock in at 20%. “P2P is in very early innings but we believe the company has the resources, capital, and experience to pursue this business line,” Chen noted.Given that the company’s leadership team brings expertise from NASA and Disney to the table, Chen argues SPCE is capable of capitalizing on the opportunity, with solid execution potentially solidifying its status as an experiential luxury brand.The positioning of its commercial space flight offering as a luxury airline experience, which is what consumers are more used to, is likely to give SPCE the first-mover advantage over others like Blue Origin. “Given the high fixed cost of operating a space tourism operation, first-mover advantage looks critical to success; and VG appears better positioned than BO to get it,” Chen mentioned.What else could give SPCE the first-mover advantage? Chen points to SPCE’s 10-plus years of technology developed with $1 billion of investment made to-date and the vertically integrated aerospace development capabilities. What’s more, SPCE has “created competitive moats in a high-barrier-to-entry industry and benefits from strong consumer demand, which should support a premium pricing structure.”Based on all of the above, Chen puts an Outperform (i.e. Buy) rating and $22 price target on the stock. (To watch Chen’s track record, click here)Are other analysts in agreement? They are. Only Buy ratings, 7 to be exact, have been issued in the last three months. Therefore, the message is clear: SPCE is a Strong Buy. With a $25.43 average price target, shares could rise 22% in the next year.

Given its recent contract awards, multiple analysts believe this company’s long-term growth prospects are strong.5-star analyst Ken Herbert, of Canaccord Genuity, recently met with AJRD’s new CFO, coming away from the discussion with his bullish thesis very much intact. The company expects the space business, which makes up 40% of sales, to be flat to up slightly, due to the recent SLS RS-25 engine order, with the core defense business (60% of sales) set to see steady growth.“While near-term margin upside is limited, we believe the revenue visibility, strong balance sheet and incremental opportunities in both space and defense contribute to a scarcity value for AJRD not reflected in the stock,” Herbert commented.That said, new programs are an essential piece of the puzzle here. Earlier in September, AJRD announced that it will build two elements of the new ground based strategic deterrent (GBSD) nuclear missiles for Northrop Grumman, which received a $13.3 billion, 8.5-year EMD contract to initiate early production of the “Minuteman IV” platform. AJRD is responsible for manufacturing a large solid rocket motor for the missile’s upper stage and the post-boost propulsion system needed to guide the nuclear warheads to their targets through apogee (the highest point of their parabolic flight arc). Weighing in on the deal, Herbert commented, “The program is expected to be substantial to both Aerojet and Northrop, with 400 active and 242 spare ICBMs expected to occupy the existing launch sites in the American West. It has been estimated that the GBSD program will be worth $63 billion during its first 20 years of life, which is likely to be extended given the longevity of the current Minuteman III deterrent.”Adding to the good news, AJRD’s backlog has increased to a record high of $6.8 billion as of Q2 2020, a 48% gain from the prior-year quarter. According to Herbert, a key driver of this growth has been the $1.8 billion NASA contract to construct 18 new RS-25 engines to support at least five additional Artemis lunar missions beyond the three currently planned. “As such, visibility into Aerojet’s business with NASA continues to look promising through 2030. Aerojet has also continued to see backlog growth on THAAD, hypersonics, Standard Missile and GMLRS,” the analyst stated. If that wasn’t enough, Herbert believes missile defense and classified hypersonics programs are likely to see solid backlog growth in the near-term.On top of this, in August, the U.S. Air Force awarded two contracts for the National Security Space Launch (NSSL) program to ULA (a Boeing and Lockheed joint venture) and SpaceX. The implication? “Aerojet Rocketdyne is seen as a winner of the contact outcome, which ensured that the company will continue to provide content on a majority of U.S. military and intelligence launches. AJRD will see its upper stage engine content double on the new ULA Vulcan rocket under this contract, which utilizes a new Centaur upper stage (the Centaur V) powered by two RL10 engines, as opposed to one RL10 on the legacy Atlas V rocket,” Herbert explained.Everything that AJRD has going for it convinced Herbert to reiterate his Buy rating. Along with the call, he maintained a $54 price target, suggesting 34% upside potential. (To watch Herbert’s track record, click here)All in all, other analysts are on the same page. AJRD’s Strong Buy consensus rating breaks down into 3 Buys and no Holds or Sells. Meanwhile, the $56 average price target brings the upside potential to 39%.
