The ski bricks are standard technic skis. The chain saw and is found in the entire series of kits. The arrow shape plate is a very common piece in all space kits back to the 1980, though the usually were grey or black. Often used for wings with hinged plates. I have literally dozens of those in my childhood lego collection. Antennas were on each an every space piece, though the thin and slender ones only started showing in the early 90ies. They’re still around.
